Trailer Stop, Turn Signal And Hazard Lamp Operation
WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
The trailer stop, turn signal and hazard lamps are controlled by the BCM. If either turn signal or the hazard lamps are turned on, the BCM supplies voltage to the trailer turn relay RH or LH to make them flash. If the BCM receives stop lamp switch signal, the BCM supplies voltage to the trailer turn relay RH and LH to make them illuminate.

When energized, trailer turn relay LH supplies power to the left stop, turn signal, and hazard lamp
